Microwave heating of the lower ionosphere

Changes in the properties of the lower ionosphere due to ohmic heating of the plasma by the solar power satellite (SPS) microwave power beam are considered. The development of a predictive model of the underdense interaction of an electromagnetic beam and the lower ionosphere is described. The extent to which the Platteville and Arecibo experiments simulate SPS conditions is considered

Effect of Dual-Task Walking on Long-Range Correlations in People with Parkinson\u27s Disease

Parkinson’s Disease (PD) causes gait to be more variable and more random. Gait variability is related to disease severity, and may be a marker of fall risks. Gait in PD is attention-dependent, meaning a distraction while walking could be detrimental. The effects of dual-task walking on gait variability in PD are unclear (in particular fractal fluctuations). This study will determine if dual-task walking impacts stride-to-stride variability compared to normal walking in people with Parkinson’s Disease. We predict that dual-tasking will lead to more random stride-to-stride variability in people with PD, compared to controls. Also, within the PD group, we predict that a previous fall history will correlate with a larger change between normal walking and dual-task walking. 40 people with PD and 40 healthy elderly (HE) will be recruited to participate in 3 randomized trials consisting of: 1) Listening to an audio book while performing a word monitoring task and answering questions. 2) Normal walking at each individual preferred pace. 3) Walking while listening to an audio book and performing a word monitoring task and answering questions. Gait variability will be assessed using Detrended Fluctuation Analysis. While cognitive performance will be determined from performance on the word monitoring task and answering questions regarding context of an audiobook. Based on preliminary results thus far there appears to be a trend of PD having larger variability between normal walking and dual-tasking trials, but similar walking speeds. While HE has had a lower variability shift but a larger change is walking speed

Frustrated Demand for Unionisation: the Case of the United States and Canada Revisited

In this paper we demonstrate that there is a substantial union representation gap in the United States. We arrive at this conclusion by comparing Canadian and American worker responses to questions relating to desired union representation. We find that a majority of the gap in union density between Canada and the US is a function of greater frustrated demand on the part of American workers. We then estimate potential union density rates for the United States and Canada and find that, given current levels of union membership in both countries, if effective demand for unionisation among non-union workers were realised, then this would imply equivalently higher rates of unionisation (37 and 36 percent in the US and Canada respectively). These results cast some doubt on the view that even minor reforms to labour legislation in the US, to bring them in line with those in most Canadian jurisdictions, would do nothing to improve the rate of organising success in the United States. The results also have implications for countries such as Britain who have recently moved closer to a Wagner-Act model of statutory recognition.Frustrated Demand for Unionisation: the Case of the United States and Canada Revisited
